The CR200 analyzer is a UV spectrometer tuned on the absorption band of Chromium 6. It performs a selective measurement taking into account the turbidity and the presence of some
interfering species organic matter.

The UV light source is a long life time Xe lamp. The original powering electronics grants a very low energy consumption as well as a life time that exceeds 10 years. In order to ensure the best
reproducibility and accuracy of measurements, several measurements are performed within a very short time (less than 20 sec) for each analysis cycle. Any disturbance in the measurement
conditions that could affect the analysis result is detected by the probe itself and leads to a fault
alarm activation.

Any electronic disturbance likely to affect the result of the analysis is detected by the analyzer and sets a default off.

The measurement result is given in mg/l of Cr6+ ions.

The analyser is factory calibrated, it needs no routine recalibration. The UV spectrometry method makes the measurement long term reliable without drift risk.

The measurement results can be transmitted thanks to a 4 – 20 mA output that whose scale can be set by the user himself.

Advantages:

• Hexavalent chromium monitoring: 0 – 50 mg / l Cr6 +; 0 – 600 mg / l Cr6 +; Other ranges on request
• Quick results : chromium measurement in 20 seconds with no reagent needed
• Long-term reliability of the measurement: UV chromium measurement technology; Automated cleaning system and zero adjustment.
• Functional measurement of dirty water: Large section hoses : limited risk of clogging; Optical turbidity compensation.
